Definitions

  • the invention relates to an ejector device, in particular for a Multi-stage press, a cold converter and an adjustment method the lifting height of an ejector device.
  • the present invention is particularly applicable to any type of cold converter, in particular to multi-stage cold converters.
  • Such a cold converter is, for example, from EP 0 354 428 A2 known.
  • workpieces are processed in a multi-stage process cold formed by the respective workpiece from a forming station transported to another and in each of these stations from one Stamp and a corresponding die is formed.
  • the workpieces have to be formed by ejectors ejected from the die or from the stamp.
  • the present In particular, the invention relates to the field of the die side Ejector, the dies being the stationary part of the die-punch arrangement form.
  • the invention proposes an ejector device in which one operatively connected to a rotating ejector drive shaft Ejector lever drives an ejector plunger, taking on the ejector drive shaft is provided a curve along which a Cam follower runs, and the cam follower via an intermediate link drives the ejector lever.
  • the intermediate link By changing the intermediate link, the lifting height and if necessary also the periodic movement of the ejector lever can be changed in a relatively simple manner. This requires, for example the intermediate link just to be relocated.
  • the intermediate link is particularly simple in its movement controllable if the intermediate link is an intermediate link lever includes.
  • the intermediate link lever is preferably on a displaceable one Intermediate link axle mounted so that by moving the Intermediate link a displacement of the intermediate link or of the intermediate link lever directly the leverage between the cam follower, Intermediate link and ejector lever influenced.
  • the intermediate link may include an intermediate link carriage, which along at least one handlebar track on the cam follower or on the Ejector lever is displaceable.
  • This shift can on the one hand to Setting the lifting height or other changes in the motion sequence of the ejector lever can be used.
  • this shift between intermediate link and cam follower or between intermediate link and ejector lever even during the cyclical movement the ejector device, so that in the adjustment of the movement of the ejector lever to the motion sequence of the cam follower a very large variability can be guaranteed.
  • the intermediate link carriage can be force-free along a respective link path be shifted when the shift track with the handlebar track matches.
  • the intermediate link carriage bridges a distance between the ejector lever and the cam follower, so a power-free Relocation occurs when this distance along the relocation path of the intermediate link wagon remains constant. With such an arrangement can the forces required to relocate the articulated lorry are minimized.
  • the intermediate link carriage is preferably both along a handlebar track the ejector lever as well as along a handlebar path of the cam follower trained to be relocatable. With such an arrangement the intermediate link carriage is guided on a fixed assembly realize so that the movable assemblies of the ejector device do not need to be burdened with this tour.
  • the ejector device has an adjustment position in which the intermediate link carriage can be moved without this during the Relocation of the ejector lever.
  • the Adjustment position in the front dead center of the ejector lever or the ejector device so that when the movement sequence is adjusted the front dead center of the ejector lever becomes.
  • the intermediate link bridges a gap between the ejector lever and the cam follower and is along this gap it can be moved between a starting position and an ending position advantageous if the ejector lever axis on the of the gap opposite side of the starting position and the cam follower axis on the is arranged from the side facing away from the end position.
  • the ejector lever limits this space from one side and the cam follower this space from the other side.
  • the two lever arms thus range from different Sides towards the intermediate link. Now becomes the intermediate link one lever arm shortens while the other Lever arm extended. A shortening of the lever arm, with which the driving cam follower acts on the intermediate link, requires one Reduction in amplitude.
  • a roller gear be provided as part of the adjustment means.
  • Adjustment means which include a roller gear, also independent of the remaining features of the present invention in an ejector device can be used advantageously.
  • a particularly secure gear connection can be achieved if that Rolling gear drives a screw gear.
  • the ejector device 1 has a rotating drive shaft 2 which a curve 5 is provided. This curve 5 is followed by a cam follower 6, which is mounted on a cam follower axis 16.
  • the movement of the cam follower 6 is via an intermediate link, which comprises an intermediate link lever 7 and an intermediate link carriage 9, transferred to an ejector lever 3, which is an ejector plunger 4 drives in a manner known per se.
  • an intermediate link which comprises an intermediate link lever 7 and an intermediate link carriage 9, transferred to an ejector lever 3, which is an ejector plunger 4 drives in a manner known per se.
  • the ejector lever 3 pressed by a return spring 17 against the intermediate link, so that he immediately follows its movement.
  • the intermediate link is on parking surfaces 10 and 11 of the ejector lever 3 or the cam follower 6 along two handlebar tracks. Here run the handlebar tracks on the surface of the ejection lever 3 or the cam follower 6.
  • the shift takes place here in that an axis 8 of the intermediate link lever 7 is mounted in a slide 18, which can be moved along a guide 19.
  • the Carriage 18 is operatively connected to a motor drive 21 via a transmission 20.
  • a manual drive can also be provided.
  • the intermediate link carriage 9 is displaced both with a displacement of the carriage 18 as well as with the Drive shaft 2 caused ejector movements along the handlebar tracks 10 and 11.
  • the intermediate link is between a start position and an end position displaceable along the handlebar tracks 10 and 11. Bridged here he a space between the ejector lever and the cam follower. In the figure, the intermediate link is close to its initial position shown. As can be seen immediately, the axis 15 of the Ejector lever on the side facing away from this space Starting position, while the axis 16 of the cam follower 6 on the the space facing away from the end position. The cam follower 6 and the ejector lever 3 thus encompass this space from different sides, so that when the Intermediate linkage, one lever lengthens while the other shortened, or vice versa. As can be seen immediately a position of the intermediate link near its initial position very high amplitude transmission of the movement of the cam follower 6 the intermediate link carriage 9. In addition, the condition in the starting position short lever with which the intermediate link 9 on the Ejector lever 3 attacks the movement of the intermediate link carriage 9 is transmitted to the ejector lever 3 with a very large amplitude.
  • the figure shows the ejector device at the front dead center of the ejector lever 3.
  • the cam follower 6 is also in this state at the highest point of curve 5.
  • Footprints 11 and 10 of the ejector lever 3 or the cam follower 6 are designed in such a way that in this position both are parallel to each other. In this way the intermediate link can be force-free between the shelves 10 and 11 be relocated. In addition, with such an arrangement it is ensured that the front dead center always remains in the same position.
  • the ejector device 1 also has a counter stop 12 for the ejector plunger 4.
  • This counter stop 12 is by a the counter stop 12 screw adjustable. That screw is connected to a gear 13, which with its ring gear in a Tooth roller 14 engages, thus by means of a motor drive 22 serves as an adjusting means for the counter-stop 12.
  • the roller 14 and the Motor drive 22 are on a lever 23 along a guide 24 pivoted so that it can quickly be put into one for maintenance work Maintenance position can be pivoted.
